Hi Jean

What a day! Pleased however that you were all OK and lessons to be leant from your experience
A pity you went from Haslar to Hayling Island making the distance to Cowes even further. Perhaps if you had headed for Southampton Dry Stack who knows you may have caught up with us.

Agreed, even managed to squeeze a Tohatsu 3.5hp on a Pro 7. Where there's a will there's a way.

One point about an Aux - I'd not want to come into Chichester harbour with anything smaller than 20 HP on the back of a RIB of that size !

we had a 6.6 aux on a 5.4. Rattled like hell on the bracket if you are in a proper rough sea at speed and also meant a permanent imbalance to the ride. Just a pain really so we took it off.

Hardly pushed the boat anyway. Get you to shore, but still got to get someone to take you home really unless it is flat calm...in which case there is doubtfully much to panic about.

I have seen aux's strapped to the deck or back of jockeys etc but on less than about 7m it takes a shed load of room up percentage wise.

Get your engine running well and check your equipment, radio etc is up to spec, enough i reckon.

Have you got a glass external fuel filter with drain? Found these were brilliant if you get water/fuel problems due to tanks on the deck of the infamously wet SR deck!!

I am not suggesting it cant be done, just that there might be a better compromise. It all comes down to personal tastes I guess.

Imagine if Mr & Mrs KY had been coming into Chi and the main engine had faltered at just the wrong moment, there is the moment of indecision - try and restart the main or get the aux fired up. By the time it is running would the aux be able to put the situation right? Maybe, maybe not.

Personally the list of lessons learnt does not need "do not go to sea without a spare engine" adding to it. IMHO.

Ah but with no aux there is no option. If the engine dies at a truely critical moment your in the shit. With an Aux you can:
- try it (e.g. if the current conditions are ok)
- control it / keep out of harms way whilst waiting for some muscle to get you home properly
- choose to go somewhere else or wait somewhere better whilst the tide changes etc.

except that KY had been having an ongoing issue with the engine all day - so the prudent thing would have been to had the aux in place, or even running - ensuring that no time was wasted.

maybe not - but these posts: http://rib.net/forum/showthread.php?t=32760 and http://rib.net/forum/showthread.php?t=32878 suggests KY does have an aux but hadn't got round to finding a way of mounting it?

of course the day you need it you'll regret that decision and realise it would have been better to find a better way of mounting - and move a spare fuel can, or anchor/chain, to the other side to correct the imballance.

I'd much rather be safely ashore trying to work out how to get back to my car than at sea waiting for a tow.

that's odd - as until I get round to a better solution that's what I've done with mine on a sub 4m boat! A bit of bracket modification will see it mounted on the transom though.

I'm not suggesting that an aux is essential for every boat - mine did without for a long time, and my engine has never played up - but I think most people would put it higher up the list than AIS or active radar - and KY recently invested in those, with advice from the forum (who believed she had the aux covered).

I am with you on that one

A quick question for KY... Had you taken the decision to anchor in sheltered water, do you think you would have found one or both of the fuel supply problems? Would you have felt better if you did or would your other half have lost both portions of breakfast in the process?

Help I feel like I'm in the RIBnet Court for not having fitted my aux engine

Let me put my side of the story to the bench:

Your learned Clerk we did indeed try to fit an aux engine - however having rung a few local chandlers the responses we got were along the lines of: it's not possible on your transom due to the shape of the a frame, it won't push your boat along (we already have a 4hp or thereabouts and of course the 25hp from the SIB), it will cause massive vibration and unbalance the boat.

We have therefore not progressed a solution - having it inside the RIB, apart from the risk of it coming loose, didn't seem sensible as with three adults and two large fuel cans rooms is limited.

However the fundamental mistake we made was to try and come into Chi Harbour in bad weather, in poor sea conditions with a buggered engine, we were very lucky it didn't fail on the way in.

What are my thoughts in hindsight...

1. I still don't think an aux engine is the answer for us - regardless of wether you can fit them to our RIB - why .... because it would'nt have helped at all - how do I know that, when we conked out the third time (!!) we managed to get the engine running at throttle forward to a gentle 6hp (the idea to conserve fuel and hand pumping) - we went no where - in fact according to the GPS slightly backwards - I personally think an aux engine (again on reflection) offers a comfort zone that when needed will fail.

2. Could we have started an aux on the way into the harbour if it had been tied to the inside of the boat or raised on a bracket - I doubt it - we couldn't stand up let alone move around - so it would have been utterly useless.

3. We could have had an aux running and on standby ready to take over - but then that raises another issue. Our current engine has a separate oil tank - so mixes for you - our aux needs a pre mixed fuel, so we would have needed a separate fuel tank so yet another item to carry, how much extra pre mixed fuel should we take when out, and of course the need to change in the event of an emergency.

In an ideal world we should have:

1. Not left via Chichester Harbour - I knew it could be grotty but lack of preparation meant I had no idea how grotty
2. Radioed the coastguard at the first sign of trouble
3. Made for the nearest safe haven and asked Darren's Dad to collect us, returned to the trailer and then collected the RIB. - So angry at myself for this oversight!!
4. Been members of Sea Start - allowing us to moor up and wait for the breakdown service whilst not placing other people or ourselves a risk.

Malthouse - just seen your comment - no we could not have fixed the fuel tanks without unscrewing the top plates - I doubt we could have done this on Saturday - however Darren did have a very large tool kit in the boat - weighs the same as a small person - so it is a possibility - he was so unwell though!!!!!

If we had found the issues with the tanks then yes that would have solved the worry over the engine but we should never have attempted coming back through the Harbour entrance when a lift from Portsmouth would have solved the problem but just taken slightly longer.

A few days after the event and I can't believe how much I've learnt through the experience, I'm obviously slightly nervous about the next time out - will be posting on here for a few friendly faces to join us - but I also feel so much more prepared and confident of better choices if it ever happened again - and that can only have been gained through the experience of Saturday

Once again thank you so much to everyone on here for sharing their advice and asking further questions - it is genuinely very much appreciated

For what it is worth, I reckon that by not being fair weather boaters you have gained a big chunk of experience and will be all the better for it.

That which does not kill us.... yada yada yada

Do not feel bad about the aux engine thing, to some people you are daft not to have one and to others they are a waste of space. Getting the two groups together over beer is always lively!
